On a typical x86 motherboard, are the PIT (Programmable Interval Timer)
and LAPIC (Local Advanced Programmable Interrupt Controller) timer
driven by the same crystal?
In other words, will ntpd compute a similar frequency offset if I switch
from PIT to LAPIC timer?
Is the LAPIC timer in any way "better" than the PIT (resolution?
precision? accuracy? overhead? anything else?)
